RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a prese- lector. The bandwidth of the spectrum analyzer was 100 kHz with an appropriate sweep speed. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The resolution bandwidth was 100KHz and the video bandwidth was 300KHz. The ambient temperature of the UUT was 81.1oF with a humidity of 25%. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was estab- lished by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor sup- plied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the Preselector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) METER READING + ACF = FS 33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m FCC ID: M48T432S REPORT #: T:\CUS\C\CAME\CAM52U0\CAM52U0.RPT PAGE #: 1 TEST PROCEDURES CONTD. ANSI STANDARD C63.4-1992 10.1.7 MEASUREMENT PROCEDURES: The UUT was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The UUT was placed in the center of the table. The table used for radiat- ed measurements is capable of continuous rotation. The spectrum was scanned from 30 MHz to 10th harmonic of the fundamental. Peak readings were taken in three (3) orthogonal planes and the high- est readings were converted to average readings based on the duration of "ON" time. Measurements were made by TIMCO ENGINEERING INC. at the registered open field test site located at 849 N.W. State Road 45, Newberry, Fl 32669. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1m to 4m. The antenna was placed in both the horizontal and vertical planes. RULES:2.1033(b)(4) CIRCUIT DESCRIPTION This unit is a low power security device transmitter. The oscil- lator is a SAW oscillator formed by the transistor T3 and the SAW filter Q2 tuned circuit made up of antenna L4, C5, C9, & C182. The inductor is printed on the PCB. The digital code is provided by the integrated circuit IC1. The unit is completely self contained and is powered by a 12Volt batteries. The calculations are shown in the report and the duty cycle was 39.86%. ANTENNA & GROUND: This unit uses the PCB inductor as the antenna. There is no provision for an external antenna.
